SAFENCE® is a longitudinal wire rope cable barrier system that is NCHRP 350 TL-3 and TL-4 approved. It is available in 3 or 4-wire rope cable configurations with non-releasable anchors. This is a preferred system because the wire guardrail cables remain under tension after vehicle impact. SAFENCE® meets Test Level-4 requirements with just .6 large truck impacts. This research will extend the work accomplished under NCHRP Report 663 and eliminate the need to extrapolate knowledge from a TL-3 impact to a TL-4 and TL-5 impact. Furthermore, the work documented in this report generated new information which led to modifications of the recommendations made in NCHRP Report 663. Test no. MSPBN-6 was conducted on the modified thrie-beam bullnose system according to MASH 2016 test designation no. 3–31 with an 2270P vehicle at an impact speed of 102.1 km/h and at an angle of 0.3°.
